Zhaga Consortium publishes Book 2 interface specification

February 28, 2013 // By Christoph Hammerschmidt
The Zhaga Consortium has published its second interface specification for LED light engines. Book 2 describes a cylindrical light engine with integrated electronic control circuitry. In addition, Zhaga has created a database of certified products, which are all commercially available. The database will be constantly updated as new certified products reach the market.

According to the consortium, the specs contained in the new Book are fully accessible by the entire lighting industry, not just by Zhaga members. "This allows companies to design their products to be interchangeable with other Zhaga-based products,” said Menno Treffers, secretary-general of the Zhaga Consortium.

Zhaga Interface Specification Book 2 describes a cylindrical, socketable LED light engine with integrated electronic control gear (ECG, commonly termed the driver). The light engine has maximum dimensions of 70.2 mm and 45 mm height. The diameter of the circular light-emitting surface is typically 59 mm. The light engine can be locked into a holder in the luminaire by means of a twisting motion.

One use of this type of LED light engine is in downlighting applications. A summary of the technical details of Book 2 can be found on the Zhaga website along with the full specification.

Products designed and certified according to Zhaga Interface Specification Book 2 – including LED luminaires, LED modules, holders, and LED light engines – are already commercially available from a range of different suppliers. A database of all the Zhaga-certified products can be found on the website. Currently the database contains 63 product descriptions.

“The availability of Zhaga-certified products demonstrates that the specifications developed by Zhaga are being utilized by a range of companies in the lighting industry,” Treffers said. “Other products are currently going through the certification process, and we expect to add many more products to the database in the coming months.”

The Zhaga Interface Specification Book 2 can now be downloaded from the Book 2 page on the Zhaga website
